All ES1, ES3 and ES5.1 features should be implemented (to some degree...), but conformance is always work in progress.
You need a modern C++ compiler that supports C++17 and CMake 3.7 or later. It has currently been tested with the following compilers:
- Visual C++ 2017 15.9.6 on Windows 10
- GCC 8.2.0 (x64 distribution from Stephan T. Lavavej) on Windows 10
- GCC 8.2.0 (on x64 Linux, Debian testing as of October 2018)
- Clang 7.0.0 (on Windows 10 and x64 Linux)
To run the tests build the
The interpreter is built in the
file on the command line or starts in REPL mode if no argument is given.
The ECMAScript version can be chosen by supplying it as a command line
These steps should work for most people:
mkdir build cd build cmake .. # Here you may want to use e.g. CXX=g++-8 cmake .. cmake --build . cmake --build . --target check
Several debugging features can also be enabled. Use your favorite CMake GUI to view and toggle them (they are all off by default).
The project is currently light on the documentation front, but here is what's available so far:
- Implementing a Garbage Collector in C++ about how the garbage collector was implemented
- Implementer's Notes on Supporting ECMAScript 3rd and 5th Editions
Forget about it :) Feel free to raise an issue on GitHub, but don't expect anything to come of it.
